Quantum entanglement in condensed matter systems

N Laflorencie - Physics Reports, 2016 - Elsevier
This review focuses on the field of quantum entanglement applied to condensed matter
physics systems with strong correlations, a domain which has rapidly grown over the last …

[HTML][HTML] Strong disorder RG approach–a short review of recent developments

F Iglói, C Monthus - The European Physical Journal B, 2018 - Springer
The strong disorder RG approach for random systems has been extended in many new
directions since our previous review of 2005 [F. Igloi, C. Monthus, Phys. Rep. 412, 277 …

Random free-fermion quantum spin chain with multispin interactions

FC Alcaraz, JA Hoyos, RA Pimenta - Physical Review B, 2023 - APS
We study the effects of quenched disorder in a class of quantum chains with (p+ 1)-multispin
interactions exhibiting a free fermionic spectrum, paying special attention to the case p= 2 …

Many-body localization in a quasiperiodic Fibonacci chain

N Macé, N Laflorencie, F Alet - SciPost Physics, 2019 - scipost.org
We study the many-body localization (MBL) properties of a chain of interacting fermions
subject to a quasiperiodic potential such that the non-interacting chain is always delocalized …

Entanglement in interacting Majorana chains and transitions of von Neumann algebras

P Basteiro, G Di Giulio, J Erdmenger, ZY Xian - Physical Review Letters, 2024 - APS
We consider Majorana lattices with two-site interactions consisting of a general function of
the fermion bilinear. The models are exactly solvable in the limit of a large number of on-site …

[HTML][HTML] Universality and quantum criticality in quasiperiodic spin chains

U Agrawal, S Gopalakrishnan, R Vasseur - Nature communications, 2020 - nature.com
Quasiperiodic systems are aperiodic but deterministic, so their critical behavior differs from
that of clean systems and disordered ones as well. Quasiperiodic criticality was previously …

Towards explicit discrete holography: Aperiodic spin chains from hyperbolic tilings

P Basteiro, G Di Giulio, J Erdmenger, J Karl, R Meyer… - SciPost Physics, 2022 - scipost.org
We propose a new example of discrete holography that provides a new step towards
establishing the AdS/CFT duality for discrete spaces. A class of boundary Hamiltonians is …

Aperiodic spin chains at the boundary of hyperbolic tilings

P Basteiro, R Nath Das, G Di Giulio, J Erdmenger - SciPost Physics, 2023 - scipost.org
In view of making progress towards establishing a holographic duality for theories defined
on a discrete tiling of the hyperbolic plane, we consider a recently proposed boundary spin …

Topological spin excitations in Harper-Heisenberg spin chains

JL Lado, O Zilberberg - Physical Review Research, 2019 - APS
Many-body spin systems represent a paradigmatic platform for the realization of emergent
states of matter in a strongly interacting regime. Spin models are commonly studied in one …

Quasiperiodic quantum Ising transitions in 1D

PJD Crowley, A Chandran, CR Laumann - Physical review letters, 2018 - APS
Unlike random potentials, quasiperiodic modulation can induce localization-delocalization
transitions in one dimension. In this Letter, we analyze the implications of this for symmetry …
